384GB DDR5 6400 ECC RDIMM kit
This 384GB kit contains six 64GB registered DIMMs built for DDR5 6400 servers. It targets data-centre and workstation platforms that require error-correcting memory at PC5-51200 speeds. The modules are not compatible with standard desktop or laptop motherboards. Buyers needing non-ECC or unbuffered memory for consumer systems cannot use this kit.
Capacity and headroom
Six ranks of 2Rx4 organisation deliver 384GB total capacity, suited for virtualisation clusters, large databases and in-memory analytics. CAS latency of 52 at 6400 MT/s provides deterministic timing for latency-sensitive workloads. The kit reaches its limit when a platform demands higher frequencies or lower latencies than the rated specification. Applications requiring more than 384GB per socket must populate additional channels or select higher-density modules.
Build and daily implications
Registered buffering and on-die ECC protect data integrity across 288-pin slots in multi-socket chassis. Operating at 1.1V reduces power draw per module compared to higher-voltage DDR5 variants. Major OEM Samsung, Micron or Hynix DRAM ensures consistent supply quality. Installers must verify that the target server board supports DDR5 6400 RDIMM population rules and 2Rx4 rank configuration before deployment.

Questions about this item
Will the 6400MHz ECC RDIMMs train correctly in a server that still has 1.1V DDR5 modules populated?
All six modules run at 1.1V and 6400MHz PC5-51200, so they match the voltage and speed of any other DDR5 6400 DIMMs already installed; the memory controller will negotiate a single common frequency for the whole channel.
How can I verify the kit is running at its rated 6400 speed and CAS 52 after installation?
Check the BIOS memory information screen or a tool such as dmidecode; it should report 6400 MT/s, CAS latency 52, 1.1V and registered ECC operation for each of the six 64GB DIMMs.
Does the package contain only the six 288-pin RDIMMs or are any cables or brackets included?
The box holds the six 64GB 288-pin ECC RDIMMs only; no cables, brackets or additional hardware are supplied.
